Abstract

Using the ARGUS detector at the e⁺e^- storage ring DORIS II at DESY, we have observed parity violation in the decay Λ^±_c → Λπ^±. We measure the coefficient of parity violation, α_Λc, to be -0.96±0.42. In addition, we measure σ BR (Λ⁺_c → Λπ⁺ and σ BR (Λ⁺_c → Σ⁰π⁺) to be, respectively, (2.2±0.3±0.4) pb and (2.0±0.7±0.4) pb.
